1.4. Additional Resources
To find more information about resource control under systemd, the unit hierarchy, as well as the kernel resource controllers, see the materials listed below:
Installed Documentation
Cgroup-Related Systemd Documentation
The following manual pages contain general information on unified cgroup hierarchy under systemd:
systemd.resource-control(5) — describes the configuration options for resource control shared by system units.systemd.unit(5) — describes common options of all unit configuration files.systemd.slice(5) — provides general information about .slice units.systemd.scope(5) — provides general information about .scope units.systemd.service(5) — provides general information about .service units.
Controller-Specific Kernel Documentation
The kernel-doc package provides a detailed documentation of all resource controllers. This package is included in the Optional subscription channel. Before subscribing to the Optional channel, see the Scope of Coverage Details for Optional software, then follow the steps documented in the article called How to access Optional and Supplementary channels, and -devel packages using Red Hat Subscription Manager (RHSM)? on Red Hat Customer Portal. To install kernel-doc from the Optional channel, type as
root:
~]# yum install kernel-doc
~]# yum install kernel-doc
After the installation, the following files will appear under the
/usr/share/doc/kernel-doc-<kernel_version>/Documentation/cgroups/ directory:
